值得一提的是，Trillium Therapeutics的CD47抗体项目为SIRPαFc融合蛋白，与Hu5F9-G4具有相类似的CD47亲和力(nM级别)。而SIRPαFc具有两大优势: 首先是其分子量更小约80kDa，相对于抗体分子的150kDa具有更好的穿透性和组织分布性；其次SIRPαFc对于红细胞的亲和力要远远低于Hu5F9-G4，表明其可能具有更好的安全性。

CD47 is a cell surface receptor comprised of an extracellular IgV set domain, a 5 transmembrane domain, and a cytoplasmic tail that is alternatively spliced. Two ligands bind CD47: signal inhibitory receptor protein α (SIRPα) and thrombospondin-1 (TSP1). CD47 expression and/or activity has been implicated in a number of diseases and disorders.

However, the CD47 inhibitor space is In addition, a blocking monoclonal antibody against CD47 enabled phagocytosis of ALL cells by macrophages in vitro and inhibited tumor engraftment in vivo. Significantly, anti-CD47 antibody eliminated ALL in the peripheral blood, bone marrow, spleen, and liver of mice engrafted with primary human ALL. Trillium is currently running a Phase I clinical trial of its anti-CD47 recombinant fusion protein, TTI-621, in patients with hematologic and solid tumor cancers, as a monotherapy and in Based on this key function, therapeutics targeting CD47 or its ligands thrombospondin-1 and SIRPα could have broad applications spanning reconstructive surgery, engineering of tissues and biocompatible surfaces, vascular diseases, diabetes, organ transplantation, radiation injuries, inflammatory diseases, and cancer. PMCID: PMC3564224 Apr 15, 2021 (Heraldkeepers) -- The Leukocyte Surface Antigen CD47 market report provides a detailed analysis of global market size, regional and CD47 also mediates inhibitory thrombospondin-1 signaling in vascular cells, T cells, and NK cells, and blocking inhibitory CD47 signaling on cytotoxic T cells directly increases tumor cell killing. Therefore, CD47 functions as an innate and adaptive immune checkpoint. •CD47 is a widely expressed glycoprotein that delivers a “DO NOT EAT” signal to macrophages through SIRPα •Binding of CD47 to SIRPαinhibits macrophage cytoskeletal activity and in turn phagocytosis •Tumor cells frequently exploit the CD47-SIRPα axis to evade immune surveillance by macrophages •Many hematologic and solid tumors express high levels of CD47 •High CD47 expression often correlates with aggressive disease and poor clinical outcomes CD47 is a membrane protein expressed in almost all cell types.
